auto glossary/dictionary?

[eluser]michaelh99[/eluser]
I think now that my question was pre-Flu (which I'm going through now) induced silliness. I have well-defined fields which I'd like to 'glossarize' ™ so having an arbitrary hook or post controller call would be overkill.

I just need to pass the text I'll be showing the user through the same sort of linkification type of function that I do now, only looking for words in the online glossary and replacing with anchor tags.
